smokeinfo - poll smokeping site for numeric information

=head1 SYNOPSIS

B<smokeinfo> path/to/config.cfg [I<options>]

  --start x			rrd graph start time. (default now-24h)
                                
  --end y			rrd graph end time. (default now)

  --filter pattern     	        search pattern for node selection

  --mode plain (default)	how to use the pattern
                                - plain
                                - recursive

  -h, --help                     display this help and exit
  --version                      output version information and exit

=head1 DESCRIPTION

SmokeInfo is a simple frontend to the L<Smokeping::Info> module. It provides
access to numeric data stored in the rrd files.

Note that --start and --end are passed directly to rrd graph. This means
they work on the same syntax. 

=head2 Examples

Get all data all nodes

 smokeinfo etc/config 

Only show nodes directly under /Customers

 smokeinfo --filter=/Customers/ etc/config

Show all nodes under /Customers

 smokeinfo --mode=recursive --filter=/Customers/ etc/config

Show all nodes with '_wlan_' in the name

 smokeinfo --mode=regexp --filter=_wlan_ etc/config
